We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:
https://discuss.afni.nimh.nih.gov
Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.
The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.
Hi Erin,
It looks like there is a problem with your design matrix and specifically with your task regressors. It maybe as simple as two regressors that are almost the same, or even identical. It maybe as complicated as one regressor being a linear combination of other regressors. You need to plot the design matrix and examine it to determine the problem's source.
